Scene 2. iMac screen turns black continuously no matter how many times you restart it.

Scene 3. When you are doing something on Mac, for example, watching a movie, the screen goes black suddenly, but the system runs still in the background.

Scene 4. It is ok with turning on MacBook Pro plugging in AC adapter, however, when you unplug the power cable, the MacBook screen will immediately go black and shut down.
